Little Mix were banned from meeting Rihanna.
The 'DNA' hitmakers and their fellow 'X Factor' contestants were told by the 'Diamonds' star's management team that they couldn't speak to her when she was a guest performer on the UK show last year.
Little Mix singer Jesy Nelson said: ''We were on 'The X Factor' with Rihanna and Lady GaGa. Lady Gaga was amazing, but we didn't get to speak to Rihanna.''
Her bandmate Leigh-Anne Pinnock added: ''Her management wouldn't let anybody meet her, but she walked past me and said, 'Your hair is awesome!' This was when I had my head half shaved, which I hated, so it cheered me up.''
However, one star the group - which also features Perrie Edwards and Jade Thirlwall - did enjoy meeting was Kylie Minogue, though they admit they couldn't stop staring at her famous butt.
Jesy told this month's issue of We Love Pop magazine: ''We met Kylie at the BRITs. I kept looking at her bum because she's got a really nice bottom.''
